Dates of the Parts of P. S. Pallas's 'Icones Insect, p. Ross. Sihir.' and 

 'Nov. spec. Quadr. Glirium.' 



To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, — As there appears to be some doubt as to the exact 

 dates of publication of the parts of the above works, the following 

 notes may be of service to your readers * : — 



Pallas, Peter Simon. Icones | Insectorum | praesertim | Eossiae 

 Sibiriaeque | peculiarium | quae | collegit et descriptionibus j 

 illustravit | Petrus Simon Pallas | M.D. | Academicus Petro- 

 politanus | Erlaagae | sumtu Wolfgangi Waltheri. | 



CIO 10 CCLXXXI. 



Part 1., pp 1-56, 3 pis. (A, B, C). 1781. [Cf. Gott. geleJir. Anz. 

 (Zug.), 1782, p. 651 ; Bohmer, Bibl. script, hist, nat., Zool. ii. 

 (2), 1786, p. 169.] 



Part II., pp. 57-96, pis. D, E, P. 1782. [Cf Dryander, Cat. 

 Bibl. Banks, ii. 1796, p. 214.] 



Part III., pp. 97-104, pis. G, H. 1798. [(7f. Dryander, loc. cit. 

 (not received 1796) ; Engleman ; Hagen ; et alii]. 



Part IV. Hagen, Bibl. Ent. 1863 (ii.), p. 25, is the only biblio- 

 grapher who refers to a 4th and 5th part ; but as we are 

 certain that p. 96 closed the 2nd part and pp. 97-104 all 

 belong to sig. n, we may presume that Hagen was wrong in 

 adding the Part IV. It is probable that the pis. I and K 

 which he refers to as having seen, were intended for Part IV. 

 [his " Heft 5 "]. 



Pallas, Peter Simon. Novae species | (iuadrupedum | e | Glirium

 All bibliographers agree that this was published in two parts — 

 I., 1778; II., 1779. In the Gott. gelehr. Anz. (Zug.), 1779, 

 p. 472, " Ease. I. sumtu Waltheri. 1778. Quart mit 5 Kup- 

 ferplatten [i., ii., iii., ivA., iv B.] S. 70 f [pp. 1-70]," is 

 reviewed ; hence it is evident that Ease, II. consisted of 

 pp. 71-388, pis. v.-xxvii.
